IRWIN A. SEIDERS, OF READING, PENNSYLVANIA, ASSIGNOR TO FLEXIBLE TRUCK GOR- PORATION, OF PHILADELPHIA, PENNSYLVANIA, A. CORPORATION OF DELAWARE 1 Moron can TRUCK Application filed December 12, 1928. Serial No. 325,444.

The invention relates to means for supporting the motor'frames v or casings in motor car trucks and more particularly to the type in which the frame or casing of a an electric motor is swiveled at one end to the wheel axle to which the motor is geared, and has a projecting nose at its opposite end that engages supporting means on a part of the car truck frame.

.rlo With the means at present in use for mounting such motors, it is diflicult and expensive, to remove the motors from the trucks for repairs, replacements and the like, and it is usually necessary to remove the wheels, axles and journal boxes with the motor. Also, in some cases, the brake rigging must be disconnected.

The present invention seeks to provide improved, simplified supporting means for the motor nose which will hold the motor casing against substantial vertical movement in opposite directions from its normal position and which can be readily adjusted to permit the vertical swinging movement of the motor either up or down and thus permit access to the motor or its removal without disassembling other parts.

The invention consists in the features of improvement hereinafter set forth,; illustrated in the preferred form in the accompanying drawings and "more particularly pointed out in the appended claims:

In the drawings:

Fig.1 is a view partially in elevation and partially in longitudinal section of a motor car truck, to which is applied the present improved supporting means for the motor casing. i

Fig. 2 is a plan view andFig. 3 an elevation of the supporting means, parts being shown in section in Fig. 3 on the lines 33 of Figs. 1 and 2. V v a Fig. 4 is a detail section on the line 4-4 of Fig. 3.

The present improvement is applicable, to car trucks of diiferent construction. That shown in the drawings comprises cast metal side frames 1 integrally connected by cen tral transverse members 2 that form the truck transom and which are spaced apart to receive the spring plank 3, bolster springs 4 and bolster 5, the spring plank being supported, as usual, fromthe transom members 2'by hangers 6 and cross bars 7. The truck side frames are provided with the usual pedestals 8 for the journal boxes 9 and are supported by equalizer springs and bars 11 and 12 which are carried in turn by thejournal boxes.

An electric motor is mounted on and geared to one of the 'wheel axles 13 and, if desired, each axle may be provided with a motor. As shown, the motor frame or casing 14 is swiveled at one end on the wheel axle and is removably connected thereto by a suitable axle cap 15. At its opposite end, the motor frame is provided with a nose which, in the form shown, -comprises upper and lower centrally disposed jaw lugs 16 which engage and hold. between them a transversely disposed supporting unit comprising upper and lower spring bars 17 and 18 and an interposed semielliptical spring 19. I

The improved supporting means, in. the preferred form shown, is divided and com prises upper and lower pairs of supporting arms 20 and 21 which are carried on the adjacent face of the transom member 2. 7 These arms are mounted in horizontally disposed guideways or seats formed by vertical and horizontal flanges or lugs 22 and 23 which are cast upon the adjacent face of the transom member 2. These lugs or flanges securely support the arms in operative position with the inner ends of the upper pair of arms above the end of the upper spring bar 17, and the inner ends of the lower pair. of arms 21 below the ends of the lower spring ,bar 18, as shown most clearly in full lines in Fig. 3. The arms are held in their operative positions by pairs of bolts 24 and 25 extending vertically through the horizontal flanges 23 and through holes formed in the arms.

By placingthe truckover a pit and re moving thebolts 25, the lower pair of supporting arms 21 can be moved laterall and outwardly to the ositio'n shown in otted lines" in. Fig. 3,3 1, the meterswang down= wardly about the axle and so readily removed. If the truck is taken from under a car, and the upper pins 24 removed, the upper pair of arms 20 can be similarly adjustecl laterally and outwardly and the motor swungupwardly about the axle.

Thus, the raising, lowering or removal of the motor for replacements, repairs and the likecan bereadily eflected without dismantling the other parts of the truck; Preferably, the guideways or seats formed by the flanges 22 and 23 are open at their outer sides to facilitate the insertion of the supporting arms. It isalso noted that, in-the form shown, the motor casing is provided with additional lugs 26 which will rest upon theinner ends of the upper pair of supporting arms in case the spring 19 is weakened or broken. Where, as usual, such additional safety lugs are" provided, the upper as well as the lower supporting arms must be moved outwardly to permit the lowering of the motor frame from its normal position. .With the construction shown, the weight of the motoryand the loaddue to rotation of the motor in one direction is transmitted by the upper jaw member 16 through the spring unit to the lower movable, supporting arms 21 and the load, due to rotation ofthe motor in the opposite direction, is transmitted by the lower'jaw lug throughfthe springunit to the upper pair of movable arms 20. The adjustable supporting arms 20 and 21 thus form seating members for the ends of the spring assembly or unit. It is also noted that the vertical flanges 22 on the truck transom prevent lateral displacement of the spring unit.

The invention is applicable to different types of trucks and motors and many changes can be made in the details set forth without departure from the scope of the appended claims. a v
